HY RAULIC DISINTEGRATING APPARATUS.

Be it known that I, HERBERT SAVAGE,

a citizen of the United States, residing at Cambridge, in the county ofMiddlesex and Stateof Massachusettshave invented certain new and usefulImprovements in Hydraulic Disintegrating Apparatus, of which thefollowing is a specification.

This invention relates to hydraulic disintegrating apparatus andparticularly to apparatus adapted to effect the subdivision ofmaterials, such as fullersearth and kaolin which either in their naturalconditionsfor upon being dried, are caused to disintegrate by theactionof water thereon.

An important object of my invention is to provide means inwhich massesofmaterial of the character, referred to can be readily, efiectively andveconomically transformed into grains, granules or similar smallparticles. y

A further object of the invention is to provide means in apparatus ofthe. character referred to, whereby grains, granules, or other smallparticles of a desired or predetermined size maybe obtained;

Other objectsand advantages of my in- I vention will be apparent duringthe course of the following description; 7

In the drawings wherein for purposes of illustrationjI have shown apreferred emon line 3-3 of Fig. 1, and, Fig. i is a cross section online 41 of Fig. 1. m

Referring to the drawings, the numeral 1 designates a verticallydisposed preferably cylindrical tank open at the top andprowhich mayadvantageously be made of screen of any desired mesh, preferably ofrelatively fine mjesh such as a 20 or 40 mesh screen. The partition 3may be advantageously mounted; upon .the transverse supporting rod or.bar 1,.the upperf-and lower ends of the partition being spaced. awayfrom the side of the tank 1 by. means of annular spacing rings 5 and 6,respectively.

Within the partition 3 is a sieve-drum 7 of foraminous material of acoarser mesh than the screen employed in the partition 3,

preferably of; 10 or 16 mesh screen; The clrcumferentlal portion :Of thedrum 7 is t 1 supported at itsupper end'by aring 8 havmg an inclinedoutwardlyextendingflange .9. The ring 8 is secured tothe outer end ofspokes or spider arms 10 carried by the hub 11 suitably mounted uponthevertically disposed shaft 12, as by means of the nut. I

13 and lock nut 14, engaging ,the screwthreaded lower portion 15 of theshaft12.

The shaft 12 is mounted in bearings 16 supported atthe inner ends ofradially disposed spider arms 17 bolted' or otherwise securedtofthe'tank" l and is provided with V a pulley 18 which is adaptedltoreceive power from a belt, not shown. The lower end of thecircumferential portion of the sieve-drum? is secured to a supportingring 7 -19, carriedat the outer end of the upwardly 11101111661 spokesOrspider. arms 20 extending outwardly from the shaft 21, mounted withinthe step bearings 22, carried by the supporting cross bar 1. .Disposed",within and extendmg transversely across the V sieve-drum '7, preferablyslightly belowthe longitudinal center. thereof, is a coarse supportinggrate 23and-below this and prefer ably at the lower end of thesieve-drum 7 isa finer supporting grate'2 1.

A large. inlet pipe on chute 25'fis sup- .ported at the upper portion ofthe'tank 1, discharging intoi 'gthe sieve-drum 7, ;the

flange 9 of the ring 8 extending upwardly beyond the lower portionoflsuch' pipe or chute. i I

Disposed below sieve drum is a iliquid agitator 26 having screw impellerblades 27 suitablysecured to the upper end of the shaft 28,;supported atits lower end in a step bearmg 29 and extending through the inclinedbottom2 of the w rn being provided with a stufling box 30 when itpassestherethrough. Theshaft28 receives 7 its motion. from the shaft-31,through beveled-gears 32 andi83, as shown. Extending through the sidevofthe tankl at its I lowermost portion is a relatively largeoutlet.pipe 34L, controlled" by. agate valve 35,

' through which lumpsor fparticles ofrock, sand, mica. or likerefuse'rnaybe withdrawn from 'the apparatus. Extending through theinclined bottom 2 of the tank 1, isan inlet pipe 3 6 controlled by theglobe valve 37, through which water in any desired regulated quantity iscaused to enter the tank 1. At the side of tank 1 are provided aplurality of outlet pipes 39, 4:0 and 41, controlled by suitable gatevalves, a2, a3, and t respectively, through any desired one of whichwater carrying in suspension the grains or granules of the massto be disintegrated, may be withdrawn from the tank 1. 7 f I l a In the use ofthe apparatusillustrated, lumpsof 'fullers earth, kaolin or othermaterial to be disintegratedare fed through the pipe or chute 25 intothe sieve-drum 7 which is caused. to revolve at any desired speed.-

The material fallsupon'the coarse supporting grate 23-and whilerevolving thereon, is subjected to the action of water entering the tank2 and maintained at the level therein, of the outlet pipe 39,40, or 41which is open. The action of the water upon the lumps will cause themrtodisintegrate or slake and the disintegrated particles suspended inwater,pass out through'the selective out-let pipe which is open. Materials ofthe character referred to. usually contain rock, sand, mica,

or the like, which it'is' desired to Wholly separate from thedisintegrated material,

and lumps or particles of this refuse fall first through the coarsegrate 23, then through the finer. grate 24, into the bottom of the tank1, from which may be withdrawn through the pipe 3%. In the use of myapparatus these refuse particles or lumps are'substantially wholly freed from the material-to be disintegrated and collected.

In the treatment of fullers earth and kaolin loymeans of my apparatus, Iam able to regulate the size of the" grains, granules or particles to beobtained by withdrawing the liquid carrying such grains'in suspension ata selected waterlevel and. also by regulating the velocity'of the waterpassing into and out of thetan'k 1. The higher the level at which theliquid containing the particles is. drawn off and the slower thevelocity of the current of water passing into and out of the tank'l, thefiner the grains, granules or particles'of the subdivided material willbe.

The finely divided material suspended in the water passing; out ofthetank 1 is separated'from'the water by settling or otherwise. v

In the use' of my apparatus in the treatment of fullers" earth,-I havefound that the resulting grains or granules will not impart any odor ortaste to oils treated therewith,

whereas it is well known that :dried and ground fullers" earth willimpart a noticeable taste and odor to oils treated with it.
